<listitem> <!-- 2015-11-06 [a76ef15d9] Add sort support routine for the UUID data type. 2016-02-03 [b47b4dbf6] Extend sortsupport for text to more opclasses. 2016-02-17 [f1f5ec1ef] Reuse abbreviated keys in ordered [set] aggregates. --> <para> Speed up sorting of <type>uuid</>, <type>bytea</>, and <type>char(n)</> fields by using <quote>abbreviated</> keys (Peter Geoghegan) </para>
<para> Support for abbreviated keys has also been added to the non-default operator classes <literal>text_pattern_ops</>, <literal>varchar_pattern_ops</>, and <literal>bpchar_pattern_ops</>. Processing of ordered-set aggregates can also now exploit abbreviated keys. </para> </listitem> Is it really sensible to group f1f5ec1ef together with the others? I think that one should be its own entry. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
